    摘要: A method for highly purifying human serum albumin (HSA), which comprises bringing a fraction containing HSA produced by genetic engineering into contact with a chelating chromatography carrier bound with copper ions, and eluting the HSA adsorbed by the carrier with a buffer containing ammonium chloride as an atagonist and having a pH of about 5-7.According to the method of the present invention, a component derived from yeast, which cannot be sufficiently removed by conventional purification methods for HSA produced by genetic engineering, can be removed from HSA produced by genetic engineering, and a highly purified HSA can be provided.
